Screw-On Wire Connectors
A wire nut connector twists onto two or more stripped wires and holds them together with an internal spring, with no crimping needed. Electricians, lighting and fan installers and dealers use these screw on wire connectors in junction boxes, ceiling roses and light fittings. A twist on wire connector can be taken off when a circuit changes, which makes these electrical wire connectors handy for service work.

Screw On Wire Connector for Junction Box Joints
Strip the wires to the length shown on the pack, hold the ends level and twist the connector on until it is firm and no copper shows below the skirt. A tug on each wire confirms the joint is secure. These joints suit lighting and fan circuits more than heavy power wiring, where a crimped lug is better. Each product page lists the wire combinations a size suits. Keep each size separate in the kit bag so the right one is at hand on a ladder.
Strip ends neatly with a wire stripper, and for heavier joints use cable lugs. Stock goes out direct from the manufacturer with 10-day returns, and electrical retailers can apply via our dealership programme.
